It's a very interesting case, and something I would like to do myself, since I blew btrfs onto one big partition and then realized I'd want /home separate if I played with using snapshots for apt rollback. btrfsctl seems worth including, if only to be used in a rescue scenario to access such subvolumes. > This would break the one filesystem==one mount concept currently > used by the partitioner. Yeah, rooting that assumption out of partman could be difficult. I have written a very simple partman-btrfs, and added this to its TODO. > Maybe handle like LVM, where there's a separate dialogue > for creating LVs (subvolumes), and then select individual > subvolumes on the main partitioning dialogue for mounting in a > given location. Something like this may be needed eventually anyway to support multi-volume btrfs filesystems. -- see shy jo
